Macfadyen joins both Reynolds and Jackman inDeadpool 3, and while details of his role are being kept under wraps, it’s easy to imagine him perhaps playing a villain alongsideThe Crownstar Emma Corrin,who was added to the Marvel threequel back in February.

While plot details forDeadpool 3remain largely under wraps,a new synopsis has revealed that the sequel is"Another chapter in the raunchy, violent, and of course, hilarious Deadpool series." Which, adding to the frustration, is rather vague and does not tell us much at all about the direction of the follow-up.

However, it is now hotly rumored thatDeadpool 3will see Ryan Reynolds’ Wade Wilson and Hugh Jackman’s Logan embarking on a road trip,an overall plot that Reynolds revealed some years agofollowing the acquisition of 20th Century Fox by Disney. With the idea of a road trip in mind, many have since speculated that theDeadpoolthreequel could take a decidedly Deadpool-esque meta-approach and follow Wade Wilson and Logan as they attempt to leave the crumbling Fox universe behind in favor of the MCU.

Further theories and rumors have claimed thatDeadpool 3will feature several characters from the Disney+ seriesLoki, including Owen Wilson as Mobius M. Mobius,suggesting that Wade and Logan will be up against the TVA (Time Variance Authority).The reason for their inclusion could be due to Deadpool’s desire to escape his universe, or it could be thanks to his meddling with time during the closing moments ofDeadpool 2. Either way,Deadpool 3is shaping up to be a multiversal madness of an adventure.

Directed by Shawn Levy and written by Rhett Reese and Paul Wernick,Deadpool 3is scheduled to be released on July 26, 2025, as part of Phase Six of the MCU.
